Background

The μ-opioid receptor (MOR) belongs to the superfamily of G-protein-coupled receptors. MOR mediates the analgesic and rewarding effects of morphine and other opiates as well as the actions of several endogenous opioid peptides (1). Upon binding to its ligands, this Gi-coupled receptor inactivates adenylyl cyclase (1) and activates a variety of G-beta-gamma-dependent pathways including the MAPK and the PI3K/Akt cascades (2,3). Trafficking of these receptors to and from the plasma membrane and their desensitization play a significant role in morphine tolerance (4,5). As with other GPCRs, these processes are modulated by phosphorylation at diverse sites within intracellular domains (6). Among other sites, agonist-specific phosphorylation of serine 375 in mouse (serine 377 in human) MOR is essential for its internalization (7).

μ-阿片受体(MOR)属于G蛋白偶联受体家族。MOR介导吗啡和其他阿片类药物以及几种内源性阿片肽的镇痛和成瘾效应(1)。与配体结合后,Gi偶联受体灭活腺苷酸环化酶(1),激活许多G-β-γ-依赖的途径,包括MAPK和PI3K/Akt信号级联(2,3)。这些受体在质膜和相关目的地之间的转运在吗啡耐受中扮演重要的角色(4,5)。与其他GPCRs一样,这些过程也被胞内域不同位点的磷酸化所调控(6)。在各种位点中,激动剂特异的磷酸化MOR小鼠丝氨酸375(人类丝氨酸377)是内化所必需的(7)。
